determine the year inline skates will exceed sales of roller skates?

the number of in-line skates sold between 1982 and 1991 can be modeled by the equation S=20692/9+1/9x. the number of roller skates sold during the same period can be modeled by S=26124/8-3/8x, where x is the year.

So the x value when the lines cross is the solution of

20692/9+1/9x = 26124/8-3/8x

I'd suggest clearing the fractions by multiplying both sides by 9*8 = 72

20692 + x = 26124*9/8 - 3*9/8 x

20692*8 + x*8 = 26124*9 - 3*9x
